The end play spec is 4-8 ten-thousands, which is very difficult to actually measure and much smaller and narrower of range than the 1-5 thousanths typical of my vintage Corvette and Cosworth Vega.

The nice thing is that infinitesimally adjustable pinch bolt nut. On a vintage Chevy you have a 20 thread per inch castle nut with two perpendicular cotter pin holes, so the nut has to be turned in 1/12 turn increments, which changes clearance by about .004".

Bolt down the rotor and tighten the spindle nut to a few lb-ft torque and spin the rotor a few times. Then loosen the nut just to the point where you can barely feel play by wiggling the rotor sideways and tighten the pinch bolt to lock the nut to the spindle.

You may want to do the above several times until you get a feel for when you can barely detect play.

Do a final check with the wheel installed.

As a general rule the smaller the wheel bearing end play, the more precise the steering wheel will feel. On my vintage GM cars I dressed down the washer a few thou so I could get the end play into the 1-1.5 thou range, by turning the nut an additional 1/12th turn.
